IMPROVEMENT IN WRENCHES.

Specification forming part of Letters Patent No. 195,266, datedSeptember 18, 1877 application filed August 24, 1877.

To all whom it may concern:

Be it known that I, J AGOB EISEMAN, of Galena, in the county of J oDaviess and State of Illinois, have invented a new and Improved Wrenchof which the following is a specification This invention relates to animprovement on monkey-wrenches; and the nature of my invention consistsin the combination of a detachable serrated jaw with the fixed jaw of amonkey-wrench, whereby the common nutwrench can be made to serve as apipe-wrench, as will be understood from the following description.

In the annexed drawing, Figure 1 is a side view of the improved wrench.Fig. 2 is a crosssection, showing the face of the serrated jaw.

Similar letters of reference indicate corresponding parts.

The letter A designates the shank of the monkey-wrench, on one end ofwhich is a handle, B, and on the other end is permanently secured a jaw,0, having a flat face.

The jaw D is looped on the shank A, and is caused to slide thereon byturning a screw, E. G designates a steel jaw-face, which is constructedwith a hook, a, on one end, and with a beveled and serrated surface, theteeth b of which are pitched toward the shank A. This serrated jaw G isbifurcated and secured on the shank A against the face of the fixed jawO by means of a pin,'c.

Fig. 1 shows the position of the movable jaw when it is confined in itsplace on the wrench, wherein it will be seen that the hook a passes overthe nose of the jaw G, and the pin 0 passes through the ends of thejawback of the shank. This affords a very strong attachment, and enables meto convert a common monkeywrench into a pipe-wrench.

Having thus described my invention, I claim as new and desire to secureby Letters Patent As a new article of manufacture, the removableserrated jaw G, having one end bifurcated, and a hook, a, on theopposite end, substantially as described.

JACOB EISEMAN.
